The Security Onion LiveCD can be used for Intrusion Detection. Simply boot the CD and double-click either the Snort-Sguil or SnortSP-Sguil desktop shortcuts. The Snort and Sguil daemons will then start, listening on eth0 for any suspicious traffic and creating alerts in the Sguil console.

The Security Onion LiveCD can be used to test an Intrusion Detection System. Simply boot the CD and use the included tools (such as nmap, metasploit, idswakeup, scapy, hping, and others) to test your existing IDS or to test the included Snort 2.8.4.1 and Snort 3.0 Beta 3.

The Security Onion LiveCD can be used to install an Intrusion Detection System. Simply boot the CD and double-click the Install desktop shortcut. For more information about installation, please see the README desktop shortcut.

You can read more about the Security Onion LiveCD (and, specifically, the integration of Snort 3.0 and Sguil) in my SANS GCIA Gold Paper "Snort 3.0 Beta 3 for Analysts".
